[en] In this work, we suggest using ²⁴¹Am as a proliferation-resistant burnable poison in light-water reactors. We suggest that a fuel mixture of UO₂ and ²⁴¹AmO₂ can not only prevent proliferation risk, but also reduce the burnable poison requirements. The proliferation resistance of the conventional fuel mixed with Am is enhanced by increasing the spent fuel ²³⁸ Pu/Pu ratio. Burnable poison savings are obtained by taking advantage of favorable 941 characteristics of Am transmutation chain, which allows substitution of some of the conventional burnable poison, Wet Annular Burnable Absorber (WABA), rods with the ²⁴¹Am added to the fuel mixture. In this paper, we investigate the ²⁴¹Am loading requirements necessary to obtain proliferation resistant Pu isotopic composition in the spent fuel and burnable poison requirements for the core reactivity control. Three parameters of interest that require optimization as a result of introduction of ²⁴¹Am into the fuel are the ²³⁸Pu fraction in the Pu vector at fuel discharge, the amount of excess reactivity being suppressed at the Beginning of Cycle (BOC) and the fuel
